What does p0405 mean on an exhaust gas sensor?
P0405 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Sensor Circuit A Low”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes the p0405 code on an ECM?
What causes the P0405 code? 1 The ECM monitors the EGR position sensor any time the key is on and if the sensor input signal voltage drops below a specified voltage returning to the ECM, then 2 The EGR sensor return is internally shorted to ground. 3 The EGR sensor return wiring or connection is shorted to ground.
How to fix the p0405 OBD-II trouble code?
What repairs can fix the P0405 code? 1 Replacing the EGR position sensor after the wiring is checked to be okay 2 Repairing the wiring short to the EGR position sensor or connector signal return 3 Repairing an open in the voltage reference to the EGR sensor
